Call before you take it down there but Dockside Marine in Marquette may be able to help you out. I know there are a lot of issues getting parts for those motors, I used to work marine parts for a few years back ten years ago and it was an issue then, they are also kinda a pain to work on so not a lot of mechanics are willing to. If you call Dockside they may be able to help you out or steer you in the right direction.
